Principally a form of Guilty Pleasure, the
Russell Crowe effect describes the emotion felt when enjoying a piece of creative work by a person who you consider to be a complete twat.
On the one hand you may well enjoy what the person is doing, but on the other feel a guilty twinge that you are giving your attention and money to someone you actually can't stand. This phenomenon is very similar to the
Christian Bale effect, where you may enjoy the work of someone who has disappeared up their own anus, but should not be confused with the Tracy Emin effect, where the artist is clearly both unpleasant and crap.
